Curiosity Lights Up ‘Nevado Sajama’ at Night - NASA Science NASA’s Curiosity Mars rover used LED lights on the end of its robotic arm to create this rare nighttime view of the Red Planet’s surface on

MSL Curiosity: LED lights (part of the MAHLI camera) were used to create this rare nighttime image (sol_4740, Dec. 6, 2025), focused on the “Nevado Sajama” drill in the "boxwork" structures.
